SPECIFICATION forming part of Letters Patent No. 74:7,117, dated December 15, 1903.

Application filed June 16, 1903.

To (tZZ whom it may concern:

Be it known that we, AMOS O. BANKS and GEORGE E. BANKS, citizens of the United States, residing at Baltimore, in the State of Maryland, have invented newand useful Improvements in Hangers for Freight-Oar Doors, of which the following is a specification.

Our invention relates to improvements in freight-car doors of that class in which horizontal sliding doors are employed; and it has for its object to provide the upper portion of a door with suitable hangers having substantially rectangular upper portions in which rollers are journaled to run upon an inverted right-angular guide-rail secured to a-longitudinal wooden strip by means of bolts, the wooden strip being in turn firmly secured to the side of the car-body in any suitable manner, the bottom of the door being guided by guides secured to the sides of the car and below the doorway, wherebya uniform, smooth, and steady movement of the door is accomplished in opening and closing thereof.

With these ends in view the invention consists in the novel construction and arrangement of parts, as will be hereinafter more in detail described, and particularly pointed out in the claim.

In the accompanying drawings, to which reference is had and which fully illustrate our invention, Figure 1 is a side elevation of a car having our improvements applied thereto. Fig. 2 is a transverse section taken on the line 7 7 of Fig. 1, and Fig. 3 is a detail of one of the hangers.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings by letter, A designates a car of the ordinary or of any approved construction.

fdesignates an inverted- L-shaped metallic cover-plate secured directly to the side of the car near the top and over the door by means of a lag screw or bolt f through its vertical flange.

g designates a longitudinal wooden strip rigidly and permanently'secured to the side of the car by means of a lag or screw bolt g and located parallel with and below the inverted- L-shaped metallic guide rail or way f.

h designates another IL- shaped metallic guide rail or way which is rigidly secured Serial No.161,712. (N0 model.)

with a horizontal portion resting on wooden strip 9 by means of a bolt 9 and having a vertical guard-flange, the planes of the guide rails or waysf and h being at right angles to each other, as more clearly shown. in Fig. 2 of the drawings.

'1' designates hangers, the upper portion of which are of substantially rectangular form and in the openings of which are located rollers i, journaled in bearings 71 and carried by said hangers, the lower portion of the hangers being rigidly secured to the outer face and upper portion of the car-door by bolts or other suitable fastening means.

k designates metallic L-shaped keepers or guides secured to the sides of the car by lag screws or bolts 7t and located below the dooropening and which engage the lower portion of the door and serve to guide it in its: movements when opened or closed.

The construction of these hangers is such that they allow the door to be opened or closed without binding or buckling up, the rollers running freely and preventing displacement of the door. The said rollers or wheels having no grooves nor flanges in them friction is thereby reduced to a minimum.

The wheels of these hangers can be conveniently replaced with new ones if they become broken or impaired.

As doors hung from the top have a tendency to lift off of their bearings while being opened or closed, a provision for such is made by placing the cover-plate over the hanger and wheels, and as the door raises the wheels they instantly come in contact with the coverplate, the wheels reversing their motion without any friction. This being the case it is impossible for the door to bind or look itself, there being nothing that the wheels can con tact with but the guide rail or way, which is of great importance.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

The combination with the car-body of the longitudinal wooden strip secured above the doorway and a metallic L-shaped rail with a horizontal portion secured to the top of the wooden strip and a vertical guard'flange on its outer edge and a metallic L-shaped coverplate having its vertical flange secured to the side of the carand a horizontal portion over- In testimony whereof we have signed our 10 hanging the rail, and a hanger attached to names to this specification in the presence of the door and carryilrlig a roller running on the two subscribing witnesses.

horizontal part of t e rail and between it and the cover-plate, such hanger having a rec- E tanguiar portion inside which the roller is pivoted and open above and below so as to Witnesses:

leave the roller free to engage the track be- MURRAY HANSON,
